I go back and forth on whether or not I want a pet. I like visiting people who own pets. It’s not that I don’t want the commitment, it’s just that I’m not sure what kind of pet I would like. I think I’m more of a dog person, my wife prefers cats, my daughter would probably be happier with something smaller…
What I am sure of, is that I would not want a Puffskein as a pet. I get that wizards may want a magical critter as their companion, but a ball of fluff with an impossibly long, searching tongue can politely stay out of my house.
Puffskein

Not an ‘encounter’ creature, in any shape or form. This is a little fluff-ball children throw around, after all. No, this is a pet for your adventurers and NPCs, or a very wimpy but comical familiar.
I’m sure some of your players will find the Puffskein more adorable than gross, and could possibly put the creepy-feeling tongue to good use on their adventures.
Not me though. It may be fluffy, but that spooled, nose-tickling tongue can stay far away.
